Re: spindle

When you say "spindle pressure sensor" , do you mean to sense the amount of torque the spindle is exerting to turn the tool (spindle load),
or the amount of straight line force that the tool is experiencing as it is being pushed through the workpiece? :?:

If the wires appear to be a closed contact (low ohms) and doesn't generate any voltage when the shaft is spun by hand,
then they probably are a thermal switch.

The z sign is actually meant to be an AC voltage sign , as in sine wave ~ :oops:
